What should I do if the zoom ring on my Sony SAL18250 lens is stiff?

If the zoom ring is stiff, gently rotate it through its full range several times to distribute internal lubrication. Avoid forcing the ring. If stiffness persists, consult a professional technician for servicing.

How can I achieve sharper images with the Sony SAL18250 lens?

To achieve sharper images, use a tripod to reduce camera shake. Shoot at an aperture between f/8 and f/11 for optimal sharpness. Ensure proper focus and consider using manual focus for critical shots.

What is the recommended maintenance for the Sony SAL18250 lens?

Regularly clean the lens surfaces and contacts. Store the lens in a dry, dust-free environment. Use a protective case when not in use, and periodically inspect the lens for any signs of wear or damage.
